176. Pawnee’s right where pawnor makes default –
If the pawnor makes default in payment of the debt, or performance, at the stipulated time, or the promise, in respect of which the goods were pledged, the pawnee may bring as suit against the pawnor upon the debt or promise, and retain the goods pledged as a collateral security; or he may sell the thing pledged, on giving the pawnor reasonable notice of the sale.
